Ensure that the terminals are terminated correctly.
The example below shows a possible connection between the terminals and the PCDs. In order to
avoid reflection on the communication channel, the network should be equipped with terminators.
The PCD7.T16x can be used for termination.
The configuration can be carried out either via the Setup Menu in the Web Panel or via the hardware
configuration in the PG5. In the event of changes, the existing configuration will be overwritten.
